HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 47439 i.e. 27 the largest integer that leaves a remainder zero for all numbers.
HCF of 864, 47439 is 27 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 864, 47439 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 864, 47439 is 27.
HCF(864, 47439) = 27
HCF of 864, 47439 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 864, 47439 is 27.
Highest Common Factor of 864,47439 is 27
Step 1: Since 47439 > 864, we apply the division lemma to 47439 and 864, to get
47439 = 864 x 54 + 783
Step 2: Since the reminder 864 ≠ 0, we apply division lemma to 783 and 864, to get
864 = 783 x 1 + 81
Step 3: We consider the new divisor 783 and the new remainder 81, and apply the division lemma to get
783 = 81 x 9 + 54
We consider the new divisor 81 and the new remainder 54,and apply the division lemma to get
81 = 54 x 1 + 27
We consider the new divisor 54 and the new remainder 27,and apply the division lemma to get
54 = 27 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 864 and 47439 is 27
Notice that 27 = HCF(54,27) = HCF(81,54) = HCF(783,81) = HCF(864,783) = HCF(47439,864) .
